All this files for flashing from recovery, we don't have a recovery.
For now you can install gapps by copying files manually(or via adb push) and setting right permisions. All flashable zips have a update-script file, in this file you can see copy file locations and permissions.

Thanks for this awesome image. I've managed to update my official 4.2.2 image to your port via the official updater.
However, the WIFI is not working.. It stuck at turning WIFI on, no matter the wifi dongle is plugged in or not. I tried both wifi module 2 and 3, but no luck..
Please let me know if I can do anything to help you figure out this issue.
